the derogatory notion that goes with the word is basically the only reason it is honestly the same with a lot of nono words in society like the word retardation is a good comparison in my eyes i know so many many people who consider the word retardationretard to be a vulgar mean word purely because so many people use it now as an insult dictionary definition wise the word is accurate and harmless imo but socially unacceptable because it is and has been used so viciously as an insult tranny is the same in my mind in regards to why it is a bad word so to speak other things to not ever ever ever say is even jokingly use the phrase trap in regards to transgendered people its probably an obvious one but a huge no no so figured id throw that in
